STEAM AppIication filed May 20,

This invention relates to apparatusof a class commonly knownk as steam boards employed generally for the steaming of fabrics to eliminate wrinkles, raise the nap of said fabrics and the like, and has reference more particularly to apparatus commonly known as a steam sleeve boards; an object of the invention being to provide an improved construction for machines of the above class wherein means are provided for heating the machine prior to the admission of the operating steam in order to prevent condensation of said steam through contact with cold parts of said machine during operation thereof.

A further object of the invention is to be found in the provision of means for trapping and removing water of condensation which may collect in said machine. My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my i claims and illustrated by the accompanying drawing, in which- Figure 1 is an elevation of my improved device assembled and ready for use. Figure 2 is a cross section on an enlarged scale on the indicated line 2 2 of Figure 1. Figure 3 is a longitudinal section on ,an enlarged scale on the indicated line 3-.3 of Figur-e 2. Figure 4 is a vertical section of a modified form of my invention. Figure 5 is a cross section on an enlarged scale on the indicatedl line 5-5 of Figure 4i. Figure 6 is a vertical section of anoth'er modified construction of r my invention. Figure 7 is a cross section on an enlarged scale on ythe indicated line l1-7 of Figure 6. Figure 8 is a fragmentary vertical section of a portion of the head and standard shown in Figure 1.

In the construction of my device as shown, the numeral 10 designates generally a steam or working head, substantially cylindrical in form, closed at its ends and preferably formed of a suitable metal by moulding or casting. A chamber 11 is formed within said head 10, longitudinally thereof and eX- tends the length of said head between the closed ends thereof; said chamber being eccentric of said head .in such manner as to provide a greater thickness in the upper wall of said head than in the lower wall. Parallel, longitudinal bores 12, in this instance three in number, are formed in the upper, thicker wall of the head 10, above and parallel with the chamber 11, said bores ybeing closed at one end adjacent the end of 1,620,753 PATET reina.

ing formed with a bore communicating with Q the chamber 11., said bore being internally screw-threaded and adapted toreceive the threaded end of a support or pedestal 16. The support 16 may he of any form or construction desired, the particular forni illustrated, comprising a tubular stein portion threaded at its upper end and divided near its lower end to form bracing leg portions provided with iianges adapted to besecurcd to a floor or the like, being but one of manv suitable constructions. A chamber 17 is formed in the upper end of the support 1G and is open at its upper end communicating through the bore in the boss 15 with the chamber 11 of the head 10. A steam pipe or line 18 leads from a source of steam (not shown), the threaded end of said line being` received by the internally threaded end portion of the neck 13, said line being provided with a valve 19 adjacent the head 10, whereby the flow of steam through said line may be controlled. A branch line 2O is connecte-d to th-e steam line 18 between the source of steam and the valve 19, sai-d branch passing` through a threaded hole in one end of the head 1() and extending longitudinally the length of the chamber 11, within said chamber, and terminating in an open end adjacent and slightly spaced from the other end of said head. A pipe 21 is tapped into the support 16 in communication with. the bottom of the chamber 17 and leads through a control valve 22 to any suitable place for the discharge of exhaust steam and water.

In the modified construction shown in Figures 4 and 5, an elbow 15 is formed with a threaded bore adapted to receive and engage the threaded end of the support 16 and a stepped bore at right angles to said first bore and communicating' therewith. A cylinder 10', closed at one end and provided with external threads adjacent its open end is formed of sheet metal or the like with perforations 14 in the top portion of its curved surface and is adapted for threaded engagement with the larger of the bores in the elbow 15. A second cylinder 11', closed at one end and provided lwith eXternal threads adjacent its open end is adapted for threaded engagement with the lesser of the bores in the elbow 15"'a1n`d't is' thereby 'posi tioned within and spaced from the cylinder 10. The steam line 18, in this construction, connects with the space between-the cylinders 10 and 11 through the valve 19 and the elbow 15 fandhthef'branch line.20f.ex tends' through the elbow 15 within and nearly to the closedv endv of t-hecylinder- 11.. AThe pipe 21 is branched inthis construction, 2

In the construction'shown in.` Figures 6 Y- and'?, a cylinder 11 4is tormedwyith an internally threaded 'boss 'to 'wreceive Lthe threaded end of the support. 16,said cyllinder being hollow, closed at both ends and provided 'with f diam'etrically opposite,y downwardly extending ears longitudinally of'lits' curved surface. "A 'semi-circular #steam chamber 10 Vis formed of v'sheetn'1etal,:1s provided'with closed ends and yperforations onL its uppery `convex -surface==and isfformed with' marginal "fllanges adaptedfto engage f beneathV the ears 'ofthe cylinder 11 `and 'position' thesteam chamber V10'fonf'and` in Contact 'with said cylinder. `1n this-eonstruction ythe steam' line f 18A communicates Y through the valve 19-witlrfone =end'fotyfthe` chamber 10 and `thebranch 520 passes 'through oneend ofthecylinderi11q.and

In the operation of fmy 1devi'ce,"the" valve constructions .shown is the same as above recited, save that, as shown' in Figure 4, provision is made for draining the'cylinder 10 through the chamber 17 while the cylj inder" 114 is'draine'd by a branch of the pipe V21.
